PLIER WRENCH.

Application filed. September 3, 192%.

To all whom it may concern:

Be it known that I, HARVEY \V. Snnsnn, citizen of the United States, residing at over, in the county oi Tuscarawas and state of Ohio, have invented a new and usc'tul Plior Wrench, of which the followin is a specification.

This invention aims to provide novel means for operating the dog in a wrench ot the pliers type.

In the accompanying drawings Figure 1 represents a side elevation of a wrench constructed in accordance with this invention Fig. 2 is a similar view of the under jaw at the wrench;

Fig. 3 is an edge view oi the wrench; and

Fig. 4 is a transverse section taken on the l-4 of Fig. 1.

The wrench claimed comprises a first lever 8 and a second lever 13, the ievers having cooperating jaws 5 and 12. The second lever 18 has an elongated opening 11 dispose intermediate the ends of the second lever, and that lever has a rack 17 located along one edge of the opening 11, the first lever 8 having a circular aperture 3 located :intern'iediate the ends of the first lever- A pivot element 21 connects the levers 13 and 8 and is located in the opening 11 of the second lever 13 and in the aperture 3 of the first lever 8. A dog 20 is disposed in the opening 11 oi the second. lever 13 and is mounted to swing on the pivot element 21, spring means being provided for maintaining the dog yieldably engaged with the rack 1?. The Wrench embodies means whereby the first lever 8 will detach the dog 20 from the rack 17, when the levers 13 and 8 are swung apart to a predetermined angle. The wrench is characterized patentably by the factthat said means embodies an integral projection 22 on the dog 20, disposed radially with respect to the pivot element 21, the first lever 8 being supplied with an arcuate recess 4 communicating with the aper- Serial No. 735,645.

ture 3 of the first lever 8 and receiving the projection 22 of the dog for limited movement, the levers 8 and 13 being of singlelayer form, and being superposed one on the other (meaning thereby that one lever does not fit within the other), the construction being such that the levers may be separated simply by removing the pivot element 21, and without loosening the projection 22 or separating it from the dog 20.

I claim:

A wrench comprising first and second levers having cooperating jaws, the second lever having an elongated opening disposed intermediate the ends of the second lever, and having a rack located along one edge of the opening, the first lever having a circular aperture located intermediate the ends of the first lever, a pivot element connecting the levers and located in the opening of the second lever and in the aperture of the first lever, a dog disposed in the opening of the second lever and mounted to swing on the pivot element, spring means for maintaining the dog yieldably engaged with the rack, and means whereby the first lever will detach the dog from the rack when the levers are swung apart to a predetermined angle, the wrench being characterized by the fact that. said means embodies an integral projection on the dog, disposed radially with respect to the pivot element, the first lever being supplied with an arcuate recess communicating w""h the aperture of the first lever and receiving the projection of the dog for limited in cment, the levers being of single-layer it'oiin, and being superposed one on the other, the construction being such that the levers may be separated simply by removing the pivot element, and without loosening the projection or sepa rating the projection from the dog.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature.

HARVEY W. SEIBER.
